...If you want to hear a difference when driving then I would recommend getting the magnaflow set-up.
+1 but i would leave the resonators, i have a rasp and i'm thinking the res delete is the culprit.
If you don't want the loud sound that come with the glasspacks, I believe you can just reverse the direction when you install them. IIRC, they have directional "fins" inside of them. I don't know how much an x pipe is, but a couple of those should take care of the rasp too.
That would be correct. Cheap way to fix that, go buy a couple cherry bomb glasspacks and put them in where the resonators should be. They're about $25 each rather than the $75 or $100 that you could expect to pay for OEM parts, and they do the same exact thing.
Sure you can have them put back in. That's what I would do if I were you. Also, did you do bigger pipe from the resonators back to the muflers?
